Thermodynamics and Entropy Loss in Nanoconfined Chain Polymerization

Journal of Polymer Science, EarlyView.
The difference in the entropy change on propagation in nanoconfined and bulk free‐radical polymerizations is 1–2 orders of magnitude larger than the conformational entropy lost in confined SAW simulations. The experimental confinement entropy is also super‐extensive in chain length scaling, suggesting that the difference between experiments and ...

Quadrature Mismatch Shaping Techniques for Fully Differential Circuits

, 2008
ADCs require a feedback path for both the I and the Q part of the complex feedback signal. A complex DAC could give this feedback with near-perfect I/Q balance.

Progressive emergence of canopy gravity waves during the afternoon–evening transition

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Large‐eddy simulations are used to investigate the afternoon‐to‐evening transition of turbulence over a forest canopy and its coupling with atmospheric boundary‐layer dynamics. As surface cooling strengthens stability and weakens near‐canopy winds, canopy turbulence transitions progressively to internal gravity waves that dominate the evening flow ...

Data‐driven emulation of flow‐dependent background‐error variance in variational data assimilation

Quarterly Journal of the Royal Meteorological Society, EarlyView.
A machine‐learning approach is developed to emulate flow‐dependent background‐error variance within a variational data assimilation framework. The method reproduces uncertainty information that would normally require a 50‐member ensemble using only five members, while maintaining comparable observation fit and forecast performance.

A Differential Quadrature Procedure with Regularization of the Dirac-delta Function for Numerical Solution of Moving Load Problem

Latin American Journal of Solids and Structures
The differential quadrature method (DQM) is one of the most elegant and efficient methods for the numerical solution of partial differential equations arising in engineering and applied sciences. It is simple to use and also straightforward to implement.

Discrete Implementations Modify the Intuition of Final Set Adjustment in Barrier Function Based Control

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper establishes an implementation‐aware framework for Barrier Function Adaptation (BFA) and shows that discrete‐time realizations fundamentally alter the logic of final‐set adjustment. In particular, sufficient conditions are derived to preserve the key benefits of BFA (predefined performance, gain adaptation with uncertain perturbation

Digital Twin‐Based Optimization of Service Availability in LEO Mega Constellations Considering Handover Delays in Open RAN

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT As non‐terrestrial networks (NTNs) become integral to future 6G systems, ensuring seamless connectivity and service continuity over low Earth orbit (LEO) satellite constellations is essential. This work investigates the impact of open radio access network (RAN) functional splits on handover performance in NTNs, focusing on minimizing service ...
